About 80% of all marine waste is plastic from bottles and packaging. This rubbish runs into rivers when it rains and then flows into the sea. Most of the rubbish sinks to the bottom of the ocean but some stays on the surface and collects in large areas like the Great Pacific Garbage Patch. The rest ends up on
beaches. Rubbish causes problems for the animals living in the
ocean. Some animals mistake rubbish for food. For example, some turtles living on jellyfish think that plastic bags are a type of food. The plastic can block their stomachs so that they starve, or it may poison the turtles. A survey by the University of Queensland showed that 50% of green turtles eat rubbish, and that figure is increasing. As six species of sea turtle are already threatened with extinction, this is a big problem.
